The following table summarizes the review area and relevant finding, auditor suggestion and risk rating.

S. NoAuditor’s FindingsAuditor’s Recommendation / SuggestionsRisk Rating
1Technology Selection:- Before moving to cloud organization (auditee) did not performed cost benefit analysis.NILLow
2Physical Access Control:- Accessibility of data should be allowed to person authorized only. Since data may be sensitive to its stakeholder.Organization should apply biometric devices so that history can be saved.


Organization should adopt maker and checker rule.

Use Audit trail to check, who access the data previously and user activity.

Use Clean Desk policy in order to secure sensitive data in paper form etc.

3Login Access Control :- In this scenario every user have unique login access control and they can access data for which they have permitted for transactions.This concepts help to prevent any unauthorized data accessibility. No user can approve or authenticate data. Eg Login id password, using network monitoring and using access control.Medium
4Audit Trail:- In this scenario we can identify who last logged in, user activity and time spent by previous users.With the help of this concept, user don’t work within the rights assigned to them in order to maintain data security and integrity, Even if anybody attempts to work beyond rights to his/her. The same is traceable. User personal accountability also exists.Medium
5Firewall:- Any data coming or going outside the organization boundary is filtered in firewall system. The system in which firewall is installed is called Beston Host.Firewall act as a security between public and private network and checks any data packets coming from outside world into private network, since it checks data packets for authentication and authorization etc. Organization should install all firewall namely proxy server, network level, application level and stateful inspection.Medium
6Data Privacy and confidentiality:- Accessibility of customer data is restricted to respective organization and its authorized personnel, not to be shared with other organization or other personnel.Organization should establish policy in such a manner to maintain data privacy with other service receiver with same cloud service provider.High
7Service Level Agreement :- Any terms and condition which is harmful for auditee organization such as block out , disruption in service.Organization and CSP should meet in order to resolve the conflict and let them know about alternates sites by which service will be provided in case of emergency failure of main sites.Medium
8Natural Disaster Events:- Organization should consider natural events such as earthquake, tsunami, flood, fire etc.Organization should have one additional BCP site with wholly IT Infrastructure in case of natural disaster so as to continuity of normal business function without disruption.High

Implication of High, Medium and Low:-

  • • High:- The issue representing a finding that organization exposed to significant risk and require immediate resolution.
  • • Medium:- The issue representing a finding that organization exposed to risk that require resolution in near future.
  • • Low:- The issue represents a finding, which don’t require action from organization.

11. Format of Report/Findings and Recommendations

As mentioned in Point No 10

12. Summary/Conclusion

As per the discussion held with the management, the BOD of the company has initiated corrective steps to overcome the “high implication findings” in observed in the audit and those, which have medium implication; BOD would take corrective action as soon as possible. Since the company has migrated to “Cloud based ERP System”, so initially it will be difficult to adopt the newer technological environment perfectly by organization as a whole. However, the management is optimistic about future guidance with respect to adoption of technological changes and impact thereof on the organization.
